Turns out I'm lactose intolerant.
For about twenty years, I couldn't consume more than very small amounts of dairy products without taking Lactaid. I could eat maybe one small scoop of ice cream without having to make a quick run to the nearest bathroom.
I ran out of Lactaid once and didn't get around to going to another town to get more at the store for a couple of months. (My local town has one small grocery store and they don't seem to carry it.) So I started eating things carefully and soon came to realize that I didn't have the issue any more! Apparently, at some point in the twenty years, I ceased needing to take Lactaid with dairy products.

The one thing I can't take at all is cheese and cheese products, but then I never could. Growing up, we didn't put cheese in our food at home. If you wanted cheese, you took a slice or two or three and put it on crackers. I saw people doing that and thought they were putting butter on crackers and so I would put butter on crackers. So I had never eaten anything with cheese in or on it until I was about 12 years old.
When i was 12 years old and a boy scout, we were on a campout at a lake in a nearby state. We had macaroni on the last night of the campout. After eating, I felt miserable and went to bed early. That night, the temperatures fell to about 30 degrees Fahrenheit. In the middle of the night, I vomited in my sleeping bag and made quite a mess. It was too cold to not be in a sleeping bag, so I slept in my vomit the rest of the night. The next morning, I felt much better, but it was too cold out to wash off.
Since then, I have avoided cheese. I have found that I can tolerate the very fresh cheeses in Indian food, but that's about it. I think that those cheeses are made by curdling milk with lemon juice and are not aged at all.
One evening in grad school, I was invited to dinner with a few other people at another couple of mathematician's home. From my first bite of the spaghetti, I knew something was wrong -- I couldn't taste it, but I could feel the effects. After the hostess assured me that she knew I was coming and so she checked carefully to make sure that there was no cheese in the spaghetti sauce, I made the mistake of eating more to be polite. All night long, I felt like I was going to vomit, but somehow I never did. The next morning, she called me up and apologized because she had read through the ingredients in the sauce again and saw that it did contain cheese. Nobody else at the dinner could tell that there was cheese in the sauce.
So other than very fresh Indian cheeses that were days old, I have only eaten cheese twice in my life and it made me sick both times. The first time at the age of 12 and the second at the age of 24 or so. I'm now older than 70 and haven't eaten cheeses in nearly 50 years.

By the way, I once found (late 1970s) a list of five animals giving milk that is consumed by humans. These were cow, horse, yak, oxen, and goat (I grew up on goat's milk). Since then, I've come across more. I don't remember all of the rest, but sheep, camel, and reindeer are among them.
